Study on the analysis and simulation of fosbury flop technique based on the sports biomechanics

WenZu Song

Fosbury flop includes three stages: run-up, takeoff and crossing bar. In this paper, the principles of sports biomechanics are implied for the analysis of the three stages in fosbury flop technique, and the dynamic model is established for the three stages of run-up, rake-off and crossing bar. Using Mathematic software to simulate the movement equation, and studying the four affecting factors of a athleteÂ’s performance: height, weight, angle of the run-up and speed of takeoff, the multivariate linear regression model was established, thus the rationality of the dynamic model can be verified. This study aims to analyze the rationality of fosbury flop technique and the existing technology and provide reasonable suggestions for the development of the sports and theoretical basis.
